Low PAH Improved Fish Smoking Stove Design Development Report
This study seeks to assess improved fish drying technologies and provide design guidance for the development of an adequately efficient fuel device that produces dried fish with low PAH levels. This report presents an overview of the fish smoking process and a review of five smoking stoves tested by SNV: three existing low-cost stove designs (Chorkor, Morrison and Open Source), plus the two higher-cost stove designs (FAO Thiaroye Technology (FTT) and Divine), with respect to performance, construction, costs, capacity, user-friendliness and PAH levels in fish. Based on this analysis, the optimal conditions for this process are recommended and a design process is outlined that resulted in two new prototype fish smoking stoves– a new build downdraft stove and a combustor to retrofit to existing stove types.
